Electrical Characteristics

4.7.1

General Purpose I/O AC Parameters

The I/O AC parameters for GPIO in slow and fast modes are presented in the Table 26 and Table 27,

respectively. Note that the fast or slow I/O behavior is determined by the appropriate control bits in the

IOMUXC control registers.
